Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy.
New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey's unprecedented rainfall.
Wind resources in the next century may decrease in many regions in the Northern Hemisphere -- and could sharply increase in several hotspot regions down south.
After a collaboration between NASA scientists and marine biologists, new research rules out space weather as a primary cause of animal beachings.
Controlled burning of forestland helped limit the severity of one of California's largest wildfires, according to geographers.
A new mapping technique shows how researchers are developing computational tools that combine cellphone records with data from satellites and geographic information systems to create timely and incredibly detailed poverty maps. Unlike surveys or censuses, which can take years and cost millions of dollars, these maps can be generated quickly and cost-efficiently.
For many Californians, last year's wet winter triggered a case of whiplash. After five years of drought, rain from October 2016 to February 2017 broke more than a century of records. In San Francisco Bay, biologists discovered a hidden side effect: All that freshwater rain can turn the tables on some of the bay's invasive species.
Extreme cyclones that formed in the Arabian Sea for the first time in 2014 are the result of global warming and will likely increase in frequency, warn scientists. Their model showed that the burning of fossil fuels since 1860 would lead to an increase in the destructive storms in the Arabian Sea by 2015, marking one of the first times that modeled projections have synchronized with real observations of storm activity.
Most people agree that chocolate tastes great, but is there a way to make it taste even better? Perhaps, according to scientists who looked at different conditions that can put a strain on cocoa trees. They say that although the agricultural method used to grow cocoa trees doesn't matter that much, the specific weather conditions do.
What if there was a better way to forecast and communicate hurricanes' damaging economic impacts, before they happen? Civil engineers have developed an innovative new approach to assessing the resiliency of coastal communities to hurricanes. They've created a 'multi-hazard hurricane impact level model,' which estimates economic damages to be caused by storms, before they happen.
New UK map of air pollution provides insights into nitrogen dioxide levels across the country and within towns and cities
Researchers have created the first ever high resolution map of air pollution in the UK. The map shows how air pollution, specifically nitrogen dioxide, changes across the country and within towns and cities, highlighting likely sources and potential clean-air refuge areas.
Sea-level rise may impact vast numbers of archaeological and historic sites, cemeteries, and landscapes on the Atlantic and Gulf coasts of the southeastern United States, according to a new study.
Higher plant species richness may not be enough to protect ecosystems from the worst impacts of climate extremes
Studies on mild fluctuations in weather have provided support for the idea that higher biodiversity results in more stable functioning of ecosystems, but critical appraisal of the evidence from extreme event studies is lacking.
An issue of global concern is the anticipated shortage of agricultural output to meet the steady rise in human population. Scientists understand that overcoming crop loss due to disease and adverse weather will be key in achieving this goal.
Researchers have developed a tornado-prediction method they say could buy as much as 20 minutes additional warning time. Using high-altitude turbulence radar can help researchers detect specific tornado signatures, with 90 percent accuracy within a 100-kilometer radius.
Outbreaks of mosquito-borne viruses Zika and Chikungunya generally occur about three weeks after heavy rainfall, research shows. Researchers also found that Chikungunya will predominate over Zika when both circulate at the same time.
A major study looking at changes in where UK birds have been found over the past 40 years has validated the latest climate change models being used to forecast impacts on birds and other animals.
From Trump to Heinz, some of America's most famous family names and brands trace their origins back to Germans who emigrated to the country in the 19th century. Researchers have now found that climate was a major factor in driving migration from Southwest Germany to North America during the 19th century.
An increasingly diverse diet among European shags at one of Scotland's best-studied breeding colonies has been linked to long-term climate change and may have important implications for Scotland's seabirds.
A brand-new theory of the opening moments during the Chernobyl disaster, the most severe nuclear accident in history, based on additional analysis.
